Product Overview

This high-quality Aftermarket Water Pump Assy is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2025) models.

The water pump assembly is the primary coolant circulation component of the engine, driven to force coolant continuously through the cylinder head, and radiator circuit to maintain correct operating temperatures. The assembly consists of the pump housing, impeller, shaft, mechanical seal, and bearing, all precision-matched to the original fitment. Degraded impeller efficiency, seal failure, or bearing wear reduces coolant circulation, leading to elevated running temperatures, overheating, and potential engine damage if left unaddressed. This aftermarket replacement is designed to match the original specification, restoring efficient coolant flow and reliable thermal management to your Yamaha NMAX 125.

Complete Part Guide

Cooling issues rarely fix themselves, they build up over time. The aftermarket Yamaha NMAX125 Water Pump Assembly (2DP-E2422-01) for 2015-2020 models keeps coolant flowing as it should, helping prevent overheating before it becomes a real problem. Built for direct installation, it delivers reliable performance under everyday riding conditions. Available now from Part Hive, enjoy same-day UK dispatch on all orders before 1 PM from our London hub.

When we see fluctuating temperature on a Yamaha NMAX-125, we look at coolant circulation first. Inconsistent pump performance is a common cause. Even if the pump is still functioning, irregular flow leads to unstable readings. We replace it with the aftermarket water pump assembly and it restores consistent coolant movement and ensures stable engine temperature.
